    13 GENI is a shared testbed i.e. multiple experimenters may be running multiple experiments at the same time.  This is possible because of the concept of a 'slice' in GENI.  A slice consists of reserved resources and the set of GENI experimenters entitled to act on those resources.  A slice belongs to a single project, and can have multiple members.  A project can have multiple slices.

     18   * The unit of isolation for experiments.   A GENI experiment lives in a slice.  An experiment in one slice is isolated from experiments in other slices.
     19   * A container for resources used in an experiment.  GENI experimenters add GENI resources (compute resources, network links, etc.) to slices and run experiments that use these resources.  An experiment an only use resources in its slice.
     20   * A unit of access control.  The experimenter that creates a slice

    1530   * Slices isolate experiments.  GENI is a shared testbed and slices ensure experimenters do not interfere with one another.
